Patent GB-279823-A (GB)
IPC: H01Q21/12
Filed: 1927-10-12
Abstract: 279,823. Esau, A. Oct. 29, 1926, [Convention date]. Atmospherics, eliminating or limiting; diplex signalling; secret signalling systems.-To avoid disturbances at the receiver, waves of such a plane polarization are radiated, e.g. by a di-pole aerial a<1>, a<2> that after passing through the transmission medium the waves are horizontally polarized and reception is effected by an aerial, e.g. a horizonal frame r which responds chiefly to that plane of polarization. The Specification as open to inspection under Sect. 91 (3) (a) also comprises the application to diplex signalling which is effected by using two different planes of polarization and the same wavelength while secrecy may be obtained by varying periodically the plane of polarization, This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to the regulation of the combustible mixture for internal combustion engines
IPC: F02D9/00
Filed: 1938-09-19
Abstract: 508,345. Fuel-injection pumps. L'ORANGE. P. Sept. 19, 1938, No. 27311. [Class 102 (i)] [Also in Groups XXVII and XXIX] In internal-combustion engines in which the injection valves are each supplied by a reciprocating fuel pump, these may deliver into a common chamber which leads to the injection valves and also to the regulated overflow valve, the pump plungers being so arranged that each reaches the end of its discharge stroke at about the mid-point of the injection period of the corresponding nozzle. Fig. 5 shows one of the plungers L operating in a pump body with a connection R to the corresponding injection nozzle. On the discharge stroke, the valve H is raised by the fuel pressure until it contacts with a spring-closed valve J, the fuel passing by a connection D to the common chamber. At the end of the discharge stroke, the plunger contacts with the valve H and lifts both valves, so that fuel is supplied to the connection R. The loading of the spring which closes the overflow valve may be varied by connections with the air throttle so as to give a, richer mixture at light and full loads than at intermediate loads ; or in heavy motor vehicles the spring loading may be reduced by means of a centrifugal governor at the speed when gear-changing takes place. Again, the loading of the overflow valve may be varied in accordance with the altitude or with supercharger pressure.

Abstract: <PICT:1116656/C1/1> <PICT:1116656/C1/2> <PICT:1116656/C1/3> An aqueous suspension of kaolin is produced by supplying water and dispersant to a tank C2 having stirring means, and supplying the kaolin to a mixer 4, the suspension being circulated through a circuit containing the mixer and tank until ready when it is discharged from both the mixer and tank.  During circulation, fluid from the tank is impelled by a pump 5 through pipes 13, 16 to the mixer and is returned from the mixer to the tank through a pipe 8. When the suspension is ready the mixer contents are drawn by the pump through pipe 20 and forced through pipes 13, 21 to discharge into the tank.  The tank is then emptied through pipes 13, 22, 24 to filters discharging to a transfer tank leading to a storage vat.  Whilst the tank C2 is discharging the mixer is connected to a further tank C1 for mixing a further charge of kaolin. The mixer (see Fig. 6) has a rotor comprising arms U1, U2, M1, M2, L1, L2 and vanes T4 at least one perforated baffle 30, and a screen 33 in front of the outlet 35. The tank C2 (see Fig. 12) has a rotor comprising radiating arms driven by and depending from a motor M, and has vertical baffles (not shown) fixed to the tank wall.  The storage vat is similar to but larger than the tank C2, and has additional curved blades (Fig. 13, not shown) at the free end of the rotor.

Filed: 1919-11-11
Abstract: 159,939. White, A. E., (U.S. Light & Heat Corporation). Nov. 11, 1919. Rotary transformers; exciting.-Continuouscurrent dynamo-electric machines for operation as rotary transformers or balancers, double-current and self-regulating generators, &c. are provided with a single fractional pitch or other winding on the armature and with two distinct sets of windings on the field magnet giving rise to fields which may be regulated independently to vary the voltages at different sets of commutator brushes. Figs. 1 and 2 illustrate a construction in which the poles 11, 12, 14, 15 are provided with coils 17 - - 20 connected in series across the mains 21, 22, and producing a field with which the brushes 7, 8 co-operate, the poles 11, 12 being of one polarity and the poles 14, 15 of the opposite polarity. The poles 13 - - 16 are fitted with coils 23 - - 26 also connected in series across the mains 21, 22 and tending to make the poles 13, 14 of one polarity and the poles 15, 16 of the opposite polarity; brushes 9, 10 co-operate with this field. The two fields cross one another substantially in the form of the Greek letter #. The coils of the armature winding have a pitch of approximately 120‹. The machine may be operated as a rotary transformer by admitting primary current through one set of brushes, for example, the brushes 7, 8 and taking current from the brushes 9, 10, or it may be driven to act as a double-current generator, currents being taken from both sets of brushes; the voltages of the circuits may be adjusted either by hand or automatically by means of rheostats 27, 28 and a reversing-switch 29. The brush 10 may be dispensed with, the two external circuits being connected between the brushes 7, 9 and 8, 9 respectively. A three-brush machine may be used to step down the supply voltage for battery-charging and arc-lighting, Figs. 12 and 21, or as a balancer on a three-wire circuit, Fig. 20, or to develop a three-wire system from a two-wire supply. Figs. 22 and 23 illustrate a double-current generator with a battery connected to the brushes 10, 11 and a lighting or other load circuit connected on the one side to the brush 10 and on the other side to the brushes 12, 13 which are joined through windings 18, 19 arranged on the poles 6, 7 so as to magnetize these with the same polarity. The windings on the other poles tend to give the poles 2, 3 one and the same polarity and the poles 4, 5 the opposite polarity; the current from the brushes 10, 11 remains unchanged in direction when the direction of rotation is reversed. An automatic rocking-switch may be added to cause current to pass through both windings 18, 19.
